offers to OISMT a set of GUIs to examine the characteristics of the OBs and the state of their execution.
OB DB:
Stores The information regarding the OB definitions and their execution
Queue Scheduler
Assist the WEAVE operator in deciding which OB is most suitable for observation.
Embodies a decision management system which shall accept various input constraints and using a scheduling algorithm, will produce a ranked list of candidate OBs to be observed.
Interfaces with the Sequencer indicating which OB to execute next or to configure in the non-observable plate
Sequencer
Set up the instrument with the definition held in the OB
Responsible for taken Calibration and Science Integrations
Executes also non-OB sequences (daily checks, TCS focus, SPE Focus….)
Interfaces with all the subsystems that comprise the WEAVE instrument:
ICS
Ensure that requests are consistent
Provides the software control and feedback framework through which WEAVE will be operated
Parameter Notice Board
WHT Global status cache
Provides a single point of reference for any WEAVE OCS client that wishes to determine the status of any part of the WEAVE control system
OCS
Software System to control and interact with the WEAVE instrument
Built upon existing ING Intrument Control System
OCS=ICS+Scheduler+Sequencer
Observation Block:
Contains the complete information required to configure the instrument and
perform integrations.
Parameter Notice Board:
WHT Global Status Cache. Centralized point of information
Quick Look Module
Analyses the science and calibration integrations providing feedback to the observer about the quality of the data obtained

The OCS is the Software (and hw) system that control the WEAVE instrument. It is also in charge of giving the user feedback about the observation

4. OCS-Current Status AIT simultaneous to Manufacturing
FDR Held on March 17
MAIT phase on-going:
SPE Control system completed
DAS: integrated with Science cameras
AG: AF2 code updated for WEAVE
Scheduler on-going
PRI FTS control system in place
PRI corrector and Rotator FDRs on next months
AIT simultaneous to Manufacturing
Achieved by:
Modularity on the design
Use of Prototypes
Simulation mode for certain systems
Distribution of copies of DAS and ICS stations
Virtual LAN
OCS ready by February 2019
